Available in PDF, EPUB and Kindle. Book excerpt: Proposed revisions are presented to those sections of the AASHO specifications for highway bridges having to do with the distribution of wheel loads on bridge decks. The static distribution of movable wheel loads was studied in a broad range of bridge types. However, the study was limited to short-and medium-span bridges; bridges with spans up to about 120 feet.

Available in PDF, EPUB and Kindle. Book excerpt: NCHRP Projects 12-26 and 12-26/1 focused on the development of simplified wheel load distribution criteria for five common bridge types -- namely slab on girder, slab, box girder, spread box beam, and multibox beam. As part of the project 12-26/1 (Phase II) a Level-2 method was also recommended which consisted of a grillage analysis. Although several computer programs are available for grillage analysis, model preparation, load placement, and calculation of wheel load distribution factors is still a major task and may be a prohibitive factor for the engineers who are not fluent in computer aided structural analysis. Therefore, the development of a user friendly computer program for calculation of wheel load distribution factors based on a grillage analysis was taken. This program would also be useful as bridge engineers begin to implement the new Load and Resistance Factor Design (LRFD) specifications. This computer program, LDFAC, is capable of computing wheel load distribution factors at any user-defined location for calculation of shear or moment. Single and multiple span (continuous) bridges may be specified. The distribution factor can be for an HS20 or any other truck. Special load configurations may be specified by the user as well. The supports (abutments and bents) may be normal or skewed, and distribution factors are calculated for both single and multiple lane loadings. Additionally, the equations obtained in Phase II of this project have been incorporated into the software. The output tables present the results of these formulas for comparison. LDFAC presents a rigorous method for calculation of wheel load distribution factors for several bridges and loadings where simple formulas are not available or applicable. The factors obtained from LDFAC can be directly incorporated into the current design procedure, providing added accuracy without complicating the design process.

This book was released on 1996 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of bridge superstructures is complicated by the geometric boundaries and loading conditions. AASHTO Bridge Specifications contain a simple procedure used in the analysis and design of steel girder bridges. This procedure is to isolate individual girders subjected to a single line of w heel loads from a design truck and then calculate the maximum bending moments. The wheel loads are positioned on the girder to produce maximum bending moment which is then multiplied by an empirical distribution factor. Recently, these factors have been updated based on finite-clement analysis and parametric studies to include major bridge parameters such as: girder spacing, span length, and cross-sectional properties. The findings of previous research reported by the authors about the performance of common finite-element modeling techniques will be employed to investigate other bridge parameters thought to influence the wheel load distribution. Previous research reported in the literature did not investigate the effect of sidewalks and railings on the wheel load distribution in steel girder bridges, the current research will employ recommended dimensions for sidewalks and railings by the AASHTO Bridge Specifications to study their influence on the wheel load distribution. A typical one-span, two-lane, composite steel girder highway bridge was selected to perform the parametric study. The bridge superstructure will be idealized using: (a) quadrilateral plate bending and stretching (shell) elements for the concrete slab, sidewalk, and railing, and space frame elements for steel girders with the centroid of girders coinciding with the one of the concrete slab; (b) eight-node brick elements for the concrete slab, sidewalk, and railing, and quadrilateral shell elements for the flanges and web of the steel girders, This research wilt report the wheel load distribution results of bridges with various combinations of span lengths and girder spacings along with the presence of sidewalks and/or railings on one or both sides of the bridge cross-section The results will serve to assess the current AASHTO practice which is conservative by ignoring the presence of sidewalks and railing when evaluating or designing highway bridges.
